powerpc/85xx: Don't set FT_FSL_PCI_SETUP if CONFIG_PCI is not set

A lot of boards set FT_FSL_PCI_SETUP directly in their board code
and don't check to see if CONFIG_PCI is actually defined. This
will cause the board compilation to fail if CONFIG_PCI is not
defined. The p1022ds board is one such example.

Instead of fixing every board this patch wraps FT_FSL_PCI_SETUP
around CONFIG_PCI so we can remove CONFIG_PCI and boards will
still build properly.
